Before going to the void data type, First let us understand the data
type concept.
In C/C++ programming language, the data types refer to an extensive
system used for declaring/defining variables/objects or functions of different
types. The type of a variable determines how much memory space it occupies in
storage and how the bit pattern stored is interpreted.
char, int, float, double, void etc.. are some of the data types
in C language.

Now coming to the void
data type..
void is basically a
keyword to use as a placeholder where you would put a data type, to represent
"no data".
void actually
refers to an object that does not have a value of any type.
When "void" type is used in function definition it means that function will not return any value.
When "void" is used with pointer type variable declaration eg: void* a or void* b etc. It means any empty type i.e. later in the program you can point any data type(int or float type variable) to a or b respectively.
